WINDOW.

Application filed September 18, 1926.

The invention relates to windows and particularly .to the kind in which a plurality of sashesv are mounted for vertical reciprocation.

The cleaning of windows especially in tall buildings has always been a great problem as far as operatingexpenses are concerned, for the necessity of employing window washers Ato be on the outside of the building l0 ,together with the hazard involved, has stimulated endeavors to construct windows enabling the cleaning or washing of both sides .of the Window `panes from the inside of the :.building.

Many ingenious attempts have been made to solve the problem, but they have not found universal recognition .because they either involved expensive construction or were not acceptable for practical reasons.

It, therefore, constitutes the principal object of the invention to provide a window which permits ready access to both sides of the window panes without requiring a person to be on the outside of the room.

Another object aims lat providing a window in which the sashes may be completely removed from the frameinto the room and conveniently replaced in operative position.

A further object aims at providing a window, in which the sashes maybe detached from the sash cords or chains and removed fin a horizontal direction.

.It is a still further object of the invention to provide a window where the sashes may be removed frontwise and in like manner installed in the frame for operation.

It is also-an object of the invention to provide certain features of construction and arrangement which will tend to enhance the usefulness and efficiency of a device of the kind specified.

'With these-and other4 equally important objects in view which will become apparent from the description of the invention, the latter comprises the means hereinafter described in the specification, particularly l pointed out in the claims .forming a part thereof, and illustrated in the accompanying drawings, in which:

Fig. 1. is afront view of a window constructed Ain accordance with my invention;

Fig. 7 is a section on the line 7-7 of Fig. 6;

Fig. 8 is a: fragmentary front view of a window having a -modiicatiom Fig. 9 is a fragmentary perspective View of the window frame shown in Fig. 8; and

Figs. 10 and 11 are sections on the lines 10-10 and 11-11, respectively, of'Fig. 8.

Referring particularly to Figs. 1-8,t`he window comprises the pulleykstiles-lO and 11 which are arranged betweeng-the( front casing 12 and the rear casing-13.

To the pulley stiles are secured vertical members known as parting stripsflt. The front and rear casings project vbeyond the inner stile face `to provide frontstops 15 and rear stopslf. The front sash-17 thus vertically reciprocates between thev front stops 15 vand the parting strip 14, whereas, the rear sash 18 lis fitted for vertical reciprocation between the parting strip -14 and the rear stop 16. As is usual.4 the. window sashes are counterbalanced through-.sash weights 19 or 2O.n whose chansor'cords 21 are trained around pulleys 22 located in slots provided in the upper Ypart ofthe stilesand thence are detachably securedto the respective sashesso that in any position, of the sashes, the same are balanced as will be readily understood by those versed inthe art.` With the exception of the detachable fastening` of the sash cords. the parts thus far described are common to all windows and do notl form per se the invention.

In order to provide for the convenient complete removal of the sashes the projecting portion of the front casing` is cutaway from the sill 23zto a. point slightly higher than the topmost edge of the rfront l sash when the latter occupies the lowermost position.` An angular member 24 is secured to front casing by hinges25 so that it may be Vswung into lfunctional position as shown 1n Fig. 3, 1n which the member 24 complements the front casing and its leg 24d abuts the 'lli turn stile or may be swung outwardly as shown in Fig. et to enlarge the opening for the front sash 17 to permit the withdrawal of the latter' in horizontal direction with the sash being held vertically. rllhis withdrawal ot the front sash, however, is only possible after an auxiliary sill 2G hingedly connected to the sill 23 is swung outwardly.

In order to secure the member 2li in 'fund tional position, a. snap loch (Fig. 3) is provided in a cut out portion thereoi comprising a casing 27 in which is arranged a catch member 9,8 extending with a nose 29 through a slot in the casing, the catch 23 in the 'form of a bell crank lever pivots on a vertical pin 30 in the casing and terminates with its other end in a thumb plate 3l which is opposite to an opening 32 in the casing 27 to aord access to said thumb plate. spring 33 is interposed between the thumb plate and the remote easing wall whereby the nose 29 is held inwardly. A cut out 34 in the pulley stile permits entry of the nose 29 and the latter is held by a detention plate 35 secured to thestile to partly cover said cut out 34.

In order to swing the angular member 2li outwardly it will be necessary to depress thethumb plate 31 against the pressure of spring 33 so as to remove the catch nose from the plate 35 whereupon the member may be swung about its hinges to idle or open position.

For the purpose of removing the rear sash the parting strip la is cut ed to the same ein `tent as the front casing and a strip 36 is secured to the pulley stile by hinges 37 so as to form a complement `:tor the parting strip or to be swung away and received within an extended slot 33 provided in the stile. The strip 36 is held in operative position by an arm 39 which is secured to the angular member' Ql and is adapted to bear against the strip 37 when said member occupies the functional position.

In order to conveniently return thestrip 36 from idle to functional position, an actuating device is provided on the pulley stile which comprises a lever 4l() (Fig. 6) pivotally arranged between upstanding lugs Lll of a plate i2 secured to the stile. rlhe free end ot said lever has secured thereto a stem 43 extending in a bore la of the stile and terminating in a thumb plate 45. Je. spring 46 is interposed between the thumb plate l5 and thevplate l2 so that the active lever end is held in retracted position. When the strip 36 is in the slot 33 and the thumb plate l5 is pressed the lever .l0 forces the strip out of the slot 33 yand into functional position as will readily appear from Fig. 6.

From the foregoing `the manner ot removing the stops will be readily understood.

At first the sill 26 is swung downwardly and both sashes are lifted to topmost position. Thereupon, the thumb plates 3l are depressed to release the angular members 24@ which are swung' out. The trent sash is then lowered and may then be taken out trom the :trame trent wise, that is, in a horizontal direction without turning` the same.

Subsequently the strip 36 is swung about' its hinges into the slot 33 and utter lowering the rear sash, it may be talren out while remaining in vertical position. lt is, of course, understood that sash cords are del tached from the sashes prior to their removal and the loose ends ot the cords are secured in any convenient manner.

ln 9 and ll, a slight modification is incorporated to simplity the construction of the vinvention and to facilitate the removal and replacement of the sashes.`

ln the present case, the angular member 2e and the strip 36 are connected so as to form a rigid structure. As indicated, a plate 50 is secured to the inner face of the leg 24a and entends with tongues 5l and 52 through slots 53 and 54e in the strip 33 and are bent over onto the strip to securely hold the same rigid to the angular member. The snap loclr and the retaining plate are sul stantially the same as described in connection with the first embodiment.

ln removing the sashes, the same are again raised to topmost position and owing to the absence ot the auxiliary sill, ,it is only necessary to depress the thumb plate 3l", whereupon the angular member 2st may be swung` out. This movement is now participated by the strip 33 so that upon lowering of the sashes, both may be simultaneously withdrawn while in vertical position after the sash cords have been detached and the loose ends temporarily secured 'for instance by securing the same to studs 55 (Fig. 9) at the lower end oli the parting strip.

ilhile the drawings disclose preferred emw bodiments ot the invention, numerous changes and alterations may be made without departing from the purview ot the invention. l, therefore, do not limit myself to the deu tails oit construction or arrangement, but wish to include all changes, rearrangements, revisions, alterations and modifications con stituting departures within the scope oit the invention as delined in the appended claims.
